Improve zip read-only filesystem

Browse source 
readdir() will now always yield an inode that's consistent with stat()
on ZipOS and Windows in general. More APIs have been updated to return
the appropriate error code when inappropriately trying to do ops, like
sockets, with a zip file descriptor. The path normalization algorithms
are now fully fleshed out. Some socket APIs have been fixed so they'll
raise EBADF vs. ENOTSOCK appropriately. Lastly seekdir() will now work
properly on NetBSD and FreeBSD (not sure why anyone would even use it)
